WATER PURIFIER.

Application filed December To all whom it may concern:

Be it known that I, FRANK KRAEMER, a citizen of the United States, residing in the city of Los Angeles, county of Los Angeles, and State of California, have invented certain Improvements in ater Purifiers, of which the following is a specification.

My invention relates to water purifiers, and more particularly to electric apparatus adapted for use in causing the precipitation of certain of the foreign matter in water without destruction of the organic matter, the object of the invention being to provide a device which is automatic in the regulation of the heat developed and thus avoiding the overheating or cooking action which is caused thereby.

In order to fully explain my invention, I have shown one practical embodiment thereof on the accompanying sheet of drawings, which I'will now describe.

Figure 1 isa side elevation of a container for water with my invention applied thereto, thesame being connected with the usual electric connection;

Figure 2 is a vertical sectional view through the invention illustrated;

Figure 3 is a top plan view of the same;

Figure 4 is a cross sectional view taken on line 4-4 of Fig. 2: and

Figure 5 is an enlarged view of one of the thermostat supports for the electrodes.

Referring more in detail to the invention as here illustrated, 1, designates a head piece of any suitable insulating material, adapted to have placed thereon the open end of a cylindrical tube, 2, preferably made of aluminum and being perforated or provided with the holes 2 in its side, the lower end of said tube being open also and being capable of being removed from the head member 1. The head member 1 may be so made as to form the cap or cover for a container, as 3, when placed therein, as indicated in Fig. 1. The head member is open in its center and is provided with two thermostatic supports, as 4 and 5, made of two kinds of metal of different expanding qualities. such as brass and steel, soldered or welded or even riveted together, as indicated in Fig. 5, wherein the two metals, 4 and 4 are shown composing the member 4. The upper ends of said supports 4 and 5, are secured to the head piece 1 as by means of bolts 6, 6, which constitute terminals to have attached thereto the wires,

7, 7, from any source of electric energy. To the lower ends of said supports, 4 and 5, are suspended two metallic electrodes, 8 and 9, preferably of aluminum and of angular or channel iron form and having their lower ends bent to an angle toward each other and arranged in such relationship to each other that they will, when together, overlie one over the other, and yet be free to move apart under the expansion of their supporting members 4 and 5, in the manner indicated in Fig. 2 by the dotted line positions.

When the terminals or electrodes are moved apart in the manner indicated by the dotted line positions, the greater is the resistance from the water which makes the circuit connection from one electrode to the other, and the closer the electrodes are together, the less is the resistance. In one case the heat is increased and in the other it is reduced. The more resistance there is from the water the less amperage there is and consequently less heat. Thus by this automatic action of the movement of the electrodes the degree of heat applied to the water is regulated and automatically controlled, and overheating is avoided.

By actual tests of water taken from the same source and divided into two parts and one part tested or treated with my device for a short time, the device being adapted to develop approximately 1-1-0 degrees, with an alternating current at 110 volts, the result showed permanent hardness 44 parts per million, temporary hardness 150 parts per million or a total of 194 parts, as against 62, 200, or a total of 262 parts per million before treating. It also showed 20.58 total solids after treating as against 26.02 total solids before treating. Total incrusting solids 10.07 after treating, as against 14.39 total incrusting solids before treating.

I am aware that many changes in details can be made in the invention without cleparting from the spirit thereof, and I do not, therefore, limit the invention to the details showing, except as I may be limited by the hereto appended claims.

I claim:

1. Ina device of the character referred to, two electrodes, at head for supporting the same, thermostatic supports for said electrodes interposed between said head and said electrdoes and adapted to move the same toward and from each other as said thermostatic supports contract and expand, and means for senseless-a e sonrceofele'ctri'c energy to said supports and electrodes.

2. In a device of the character referred to, in combination, two aluminum electrodes, having their free ends bent tovvard'eacb other to overlap each other, one above the other, a thermostatic support for each or said electrodes, said supports being each made of two different metals of different expanding, properties, "means for connecting asource cct electric energy to. said supports, and means for supporting said device in ater-,- substantially as-and for the purpose scr ed,

3; In combination -.Witha container of water, means for purifying said Water, said means comprising two electrodes adaptedto e a ende o n nto a d a a c ermost-atic support fOl-flficll of said electrodes, and means for connecting a source of electric energy "to said thermostatic supports, whereby said electrodes are automatically moved toward and from :each other substantially as and for the purpose described.

4c. In combination With a container of Water, means for purifying said Water, said means comprising a head, two electrodes-suspended therefrom, thermostatic supports connectil'ig said electrodes to said head, said electrodes having. portions adapted to over-'- lap each other as they are moved toward and from each other, and a cylindrical memher around said head and said electrodes and open to receive Water therein, substantially as described.

5. A device of'the character referred to comprising in combination With a container, a head member adapted to fit said container as a cover therefor, tWo metallic electrodes having angle portions positioned to overlap each other, thermostatic supports connecting said electrodes to said head member, means for connecting a source of electric energy to said supports, and a surrounding enclosure member around said electrodes and open to permit access of Water thereto when placed in said container, substantially as shown.

6. The method of purifying Water which consists in inserting therein two electrodes supported by thermostatic supports to be automatically moved toward and from each other to automatically increase or reduce the Water resistance for current passing from one elect-rode to the other as the heat generated by said current increases or decreases, and supplying electric current to said electrodes, substantially as herein described.
